... Leibniz introduced the idea of what he called “vis viva” (living force). “vis viva” = mv2 and was conserved in some interactions between particles. It is what we now know as kinetic energy (although we now use 1/2 mv2) The term “vis viva” continued to be used for mechanical energy up to the 1850s. B ...

The characterization of ground states
... Proof of Lemma 3. Using the above ideas it is straightforward. Let i (n) be the maximal number of particles with which any given particle can interact. Suppose a particle ̟1 is ρ-close to ̟2 . Due to the divergence of the repulsion near the hard core, the energy of the interaction of particles ̟1 an ...

... The basic unit of work is the joule(J) and is equal to the product of one newton and one meter. In the English system of measurement, the unit of work is the foot pound, the product of a force of one pound acting through a distance of one foot. In order for work to be done, there must be a force ac ...
